Aaron Poreda's celler is not Matt Thornton. Matt Thornton has done it in the big show. Whoever said that Poreda's fastball has no sink is wrong. Do you honestly think we are dumb enough to draft a one pitch pitcher who has a straight fastball? Poreda throws a sinking fastball with great precision. Make your jokes but we're not that dumb. Right now Poreda's slider is just an allusion to his fastball.
